# Implementing WildRydes Serverless Web-App with AWS

In my recent hands-on experience with AWS, I completed an insightful tutorial on [building a serverless web application](https://aws.amazon.com/getting-started/hands-on/build-serverless-web-app-lambda-apigateway-s3-dynamodb-cognito/?pg=gs&sec=tut) using several key AWS services: AWS Lambda, Amazon API Gateway, Amazon S3, Amazon DynamoDB, and Amazon Cognito. This project provided a comprehensive understanding of the components and workflow involved in creating a scalable and cost-effective serverless application.

#### Key Learnings:

1. **AWS Lambda**:
    
    * **Function as a Service (FaaS)**: Lambda enables running code without provisioning or managing servers. I learned how to write functions to handle backend logic and process events triggered by API Gateway and other AWS services.
        
    * **Event-driven architecture**: Lambda's ability to respond to various events (HTTP requests, changes in data in DynamoDB, etc.) was a crucial learning point, illustrating how serverless applications can be highly responsive and scalable.
        
2. **Amazon API Gateway**:
    
    * **API Management**: API Gateway was used to create, publish, and monitor RESTful APIs. I gained experience in setting up endpoints that invoke Lambda functions, thus creating a seamless interaction layer between the frontend and backend.
        
    * **Security and Throttling**: Configuring security features like API keys and throttling policies to protect and manage access to the APIs was an important aspect of the learning process.
        
3. **Amazon S3**:
    
    * **Static Website Hosting**: S3's capability to host static websites was utilized to store and serve the frontend assets (HTML, CSS, JavaScript). This illustrated the simplicity and efficiency of using S3 for static content delivery.
        
    * **Security**: Learning about bucket policies and IAM roles to secure the content stored in S3 was critical for ensuring that only authorized users can access the resources.
        
4. **Amazon DynamoDB**:
    
    * **NoSQL Database**: DynamoDB was employed to store application data. I learned how to design tables with appropriate partition and sort keys to ensure efficient data retrieval and storage.
        
    * **Scalability and Performance**: The tutorial emphasized DynamoDB’s ability to handle large amounts of data with high availability and low latency, which is essential for modern web applications.
        
5. **Amazon Cognito**:
    
    * **User Authentication and Authorization**: Cognito was used to manage user sign-up, sign-in, and access control. Implementing user authentication and integrating it with API Gateway to secure API endpoints provided a solid understanding of identity management in serverless applications.
        

Note : For some reason, it seems that AWS revoked public access to s3://wildrydes-us-east-1/WebApplication/1\_StaticWebHosting/website. Hence, we need to get the tutorial contents from unofficial alternatives: eg) s3://ttt-wildrydes/wildrydes-site

#### Conclusion:

This hands-on experience has significantly enhanced my understanding of serverless architecture and AWS services. By building a fully functional serverless web application ([See it here](https://awswildrydes.vivekrathee.com/)), I have gained practical insights into designing, deploying, and managing scalable and secure applications on AWS.
